Abstract:

Summary form only given. The problem of efficient image/video transmission over wireless channels is considered. Such a problem involves good compression rates and effectiveness in presence of channel failures. The proposed work includes a balanced multiple description-coding (MDC) schemes for still image based on the discrete wavelet transform (DWT) developed. This MDC includes an efficient bit allocation procedure that dispatches the source image redundancy between different channels. Extended version for video was presented, and uses the 3D scan-based DWT that involves scan-based MDC with rate or quality control. To solve this problem, redundancy between the descriptors in function of channel model and state (BER) is proposed.
